I believe she is going for the Daryl Hannah (Bladerunner) look. The hair and the eyes look right. Or she is just a coke addict. I can't tell. One is creative and one is just her.
I liked how they handled Two-Face. There are rumors floating that Rachel didn't die and is in fact going to be Cat Woman in the next movie. She was already hinted at when Lucius said his new bat suit would withstand cat attacks. Remember kids, they weren't planning on Ledger to die so Two-Face returning is probably a big possibility. I though the actor did a fine job and the makeup wasn't that over the top.
Tasteless and fabulous.
